Great! That will be very interesting. It was just guesstimation on my part but the diameter and separation of the strings looked similar to high impedance lines used in SW amateur equipment typically in the 400-600 ohm range. A couple sites I've read state that ASDL actually experiences about 100 ohms impedance as opposed to voice (600 ohms) due to the large frequency difference. If all that is true then bringing the strings closer together will lower impedance which should improve the match.
